What Is a Casino Bonus?
A casino bonus is basically a reward from gambling sites to get you playing and keep you coming back. These can be anything from welcome bonuses and free spins to cashback or VIP perks.
They’re a great way to boost your bankroll and try out new games. But here’s the catch—bonuses usually come with rules like rollover requirements and game restrictions.

How We Ranked the Best US Online Casino Bonuses
Casino Credit & Match Rate
The first thing we always check is the deposit match bonus rate and the maximum amount of cash you can win. While this is important, it’s not the key factor.
Wagering Requirements
We check the number of times you need to wager the bonus money to be able to withdraw your bonus winnings. 40x is the industry standard, and you shouldn’t be forced to grind more than that.
Deadlines & Payment Method Restrictions
We look at the time limits. Most gambling sites tend to give new users at least a week to meet the wager terms. Also, most sites restrict certain e-wallets such as Neteller and Skrill, but we don’t want to see additional restrictions.
Eligible Games & Payment Methods
We also look at the game restrictions. Most real money online casinos reserve 100% wagering contributions to slot games and specialty titles. Similarly, live dealer games are usually barred, while table games rarely contribute more than 20%.
Why Should I Use Bonuses at Real Money Online Casinos
There are many valid reasons for you to claim a casino promo in the near future. As long as you have the right approach, it can only do well for your casino gaming.
- Test Advanced Strategies: The best online casino bonuses let you experiment with strategies, like card counting in blackjack or betting systems in roulette. And you don’t risk your own money.
- Maximize High RTP Games: Use bonus funds on games with high payouts, like blackjack or certain slot games.
- Claim Multiple Welcome Bonuses: Join more than one casino affiliate website and claim all the welcome deals you can.
Comparing the Top Deposit Bonuses
Ignition: The best deposit bonus available right now, a 300% match boost worth up to $3,000, evenly split between popular slots and poker games.
BetOnline: The top deal for poker players, a 100% match deposit promo that goes up to $1,000 in poker funds through free tournament tickets.
Slots of Vegas: With just a 10x rollover, the Slots of Vegas casino grants newcomers up to $2,500 in casino cash plus 50 free spins for slot games.
Shazam: The largest promo deal in the casino industry right now, a multi-tiered package that goes up to $7,500 in bonus cash to explore a wide range of games.
Super Slots: The best casino deal for slot gaming, with 300 free spins granted in multiple increments with 0x rollover requirements.
Why Is Ignition the Best US Online Casino for Bonuses?
Ignition has topped our list of casino promos for several reasons. Essentially, it’s a solid performance on all fronts that you don’t get from other casinos.
- 300% Match Rate: If you use crypto, the match rate of this casino deal is 300% and the maximum promo cash is $3,000, which again beats many casino sites.
- Half the Bonus Is for Poker: Not every casino will grant you poker cash in their welcome deal. Well, Ignition Casino hits the sweet spot by splitting its sign-up deal 50-50 between poker and other games.
- 25x Rollover: The wagering requirements of 25x are below the industry norm of 40x. This makes it easier to unlock the cash won from this casino promo.

Payment Methods to Use for Claiming Bonuses at Online Casinos
You need to be careful when picking payment methods at US online casinos because not all of them are eligible for promo deals. Most notably, Skrill and Neteller are rarely accepted because they make bonus abuse easy. Beyond that, these are the common options.
Credit/Debit Cards
Visa and Mastercard are classic choices. They’re easy to use and get the job done quickly. That said, always check the bonus terms—some casino platforms might have limits or exclusions for card deposits.
Cryptocurrency
If you’re into crypto, Bitcoin and Ethereum are awesome. Transactions are fast, fees are low, and some crypto casinos even throw in an exclusive offer for using specific cryptocurrencies—definitely worth considering.
Interac
Interac is a go-to for Canadian players and pretty common in Canadian online casinos—it’s fast, secure, works almost everywhere. Also, you don’t share any sensitive information along the way.
Types of Casino Bonuses
| Bonus Type | Description | Pro | Con |
|---|---|---|---|
| Welcome Bonus | A bonus for new players, usually a deposit match or something like 200 free spins. | Large deposit matches. | Not that easy to clear the wager terms. |
| Reload Bonus | A bonus for existing players when they make additional deposits. | Available every week. | Lower deposit matches and bonus amounts. |
| Cashback | A percentage of your losses returned, typically weekly or monthly. | Helps soften the blow of losing streaks. | Cashback percentages are usually quite low. |
| VIP Programs | Rewards for loyal players, like exclusive games and faster withdrawals. | Impressive selection of perks for high rollers. | Requires significant spending to unlock the top benefits. |
Terms & Conditions of Bonuses at Online Casinos
Before you claim any bonuses at online casinos or even sweepstakes sites, you need to understand the terms and conditions to avoid surprises. Here are the key ones to watch out for.
- Wagering Requirements: This is the number of times you need to bet the bonus amount before you can withdraw winnings. Look for casinos with lower requirements (e.g., 10x at Slots of Vegas) for better chances of cashing out.
- Game Contribution Percentages: Not all casino games contribute equally to rollover. For example, slots usually count 100%, but live blackjack could only count 10%, while live casino games are usually not an option. Always check the fine print.
- Maximum Bet Limits: Many bonuses cap the amount you can bet per round while using bonus funds for casino games or sports betting. Exceeding this limit could void your bonus.
- Expiration Dates: Even the best online casino bonuses often come with time limits, like 7 or 30 days. Use them before they expire, or you’ll lose the bonus and any winnings.
